Semp started manufacturing radios in 1942 and made their first TV in 1953. It is the only TV manufacturer from the early days of television in Brazil that is still in business. This ad is from 1957. And the black and white picture is an original photo from my personal collection where it shows the "Esso Reporter" from one our TV channels in the 1950's watching a program on that same model of TV. The picture is from 1958.
